Brake Coach Gauge
The brake coach gauge is a virtual gauge that appears after the vehicle has come to a complete stop. It coaches the driver to brake in a manner which maximizes the amount of energy returned through the regenerative braking system. The percent displayed is an indication of the regenerative braking efficiency with 100% representing the maximum amount of energy recovery. The brake coach gauge can be enabled or disabled through the message center settings.
The IPC uses 3 messaged inputs to display the brake coach gauge. The first is the regenerative braking status, the second is the request to display the braking event feedback and the third is the amount of energy recaptured. The IPC receives the regenerative braking active and brake event data messages from the GWM over the HS-CAN3. The GWM receives the regenerative braking active and brake event data messages from the PCM over the HS-CAN1.
